Question

A current of 2 A flows through a conductor with a resistance of 5 \(\Omega\). Calculate the potential difference across the conductor.

• A. 10 V
• B. 5 V
• C. 2 V
• D. 20 V

Hint:

Ohm's law relates the current, voltage, and resistance in an electrical circuit. Make sure to use consistent units when applying this law.

Answer 1

The Correct Option is A

According to Ohm's law, V = IR, where I = 2 A (current) and R = 5 Ω (resistance). Substituting these values yields V = 2 × 5 = 10 V. Therefore, the potential difference across the conductor is 10 V.
